The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.
A controller 10 for an electric power steering system 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 9.
As shown in fig. 1, a controller 10 for an electric power steering system 100 according to an embodiment of the present invention includes: casing 1, automatically controlled board 2 and cooling fan 3.
Specifically, as shown in fig. 1, fig. 3 and fig. 5, an air inlet 11 and an air outlet 12 are provided on a housing 1, an electronic control board 2 is provided in the housing 1, a heating element 21 is provided on the electronic control board 2, and a heat dissipation fan 3 is provided in the housing 1 and located between the air inlet 11 and the air outlet 12.
Therefore, the air outside the housing 1 can flow into the housing 1 through the air inlet 11 and then is discharged out of the housing 1 through the air outlet 12, so that the heat exchange of the air flow in the housing 1 can be realized. And then when automatically controlled board 2 during operation, when the air current flows in casing 1, can carry out the heat transfer with automatically controlled board 2, and then be favorable to reducing the temperature of automatically controlled board 2, improve the reliability of automatically controlled board 2 work.
Because the heat dissipation fan 3 is arranged in the housing 1, when the temperature of the electric control board 2 is high and cannot be reduced by natural air flow heat exchange, the heat dissipation fan 3 can be controlled to operate, so that the flowing speed of air flow in the housing 1 can be increased, the air flow entering the housing 1 in unit time can be increased, the heat dissipation of the electric control board 2 can be effectively accelerated, the temperature of the electric control board 2 can be reduced, the controller 10 can effectively work in a low-temperature environment, the power-assisted steering system 100 is prevented from being reduced, the controller 10 can be kept to work under a large load for a long time, the reliability of the controller 10 is improved, and the reliability and the working performance of the electric power-assisted steering system 100 are improved.
It can be understood that, when the electric control board 2 works, the heat dissipation fan 3 is not started, and the electric control board 2 is cooled only by utilizing the natural airflow flowing heat exchange in the shell 1, so that the temperature of the electric control board 2 is reduced, and the heating speed of the electric control board 2 is reduced. When the electric control board 2 works under a large load for a long time, the temperature of the electric control board 2 can not be effectively reduced only by natural air flow heat exchange, and then the heat dissipation fan 3 can be started to realize the strong cooling effect of the electric control board 2. Thereby contributing to a cost savings for the user in using the controller 10. It should be noted that, when the heat dissipation fan 3 works, the flow direction of the airflow also flows into the housing 1 from the air inlet 11, and then flows out of the housing 1 from the air outlet 12.
According to the utility model discloses a controller 10 for electric power steering system 100, through set up air intake 11 and air outlet 12 on casing 1, set up cooling fan 3 in casing 1, thereby when the temperature of automatically controlled board 2 is higher, cooling fan 3 can be opened, and then accelerate the heat dissipation of automatically controlled board 2 effectively, reduce the temperature of automatically controlled board 2, can make controller 10 work under the lower temperature environment effectively, avoid electric power steering system 100 helping hand to descend, can keep the long-time heavy load work of controller 10, improve controller 10's reliability, improve electric power steering system 100's reliability and working property.
According to some embodiments of the utility model, cooling fan 3 is connected with 2 electricity on the automatically controlled board, and controller 10 still includes temperature sensor, and temperature sensor establishes in casing 1, and temperature sensor is used for detecting the temperature of automatically controlled board 2 and sends detection signal for automatically controlled board 2, and automatically controlled board 2 is according to detection signal control cooling fan 3's running state.
Therefore, when the controller 10 works, the temperature of the electric control board 2 can be constantly monitored through the temperature sensor, the detected temperature signal of the electric control board 2 is fed back to the electric control board 2, and the electric control board 2 can control whether the cooling fan 3 operates or not according to the received detection signal. For example, when the temperature of the electronic control board 2 is greater than the first preset temperature, it indicates that the temperature of the electronic control board 2 is higher, and the electronic control board 2 may control the operation of the cooling fan 3, so as to increase the cooling speed of the electronic control board 2 and reduce the temperature of the electronic control board 2. When the temperature of the electric control board 2 is lower than the first preset temperature, it is indicated that the temperature of the electric control board 2 is lower, and at this time, the electric control board 2 can control the cooling fan 3 to be in a closed state, so that the controller 10 is more energy-saving in use, and the use cost of the controller 10 is favorably reduced. It can be understood that the electronic control board 2 can also control the rotation speed of the cooling fan 3, so that the cooling fan 3 can not only effectively reduce the temperature of the electronic control board 2, but also reduce the energy consumption of the cooling fan 3, thereby saving the use cost.
As shown in fig. 1-3 and 7-8, according to some embodiments of the present invention, the controller 10 further includes a first switch door 4, and the air outlet 12 is provided with the first switch door 4 to open or close the air outlet 12 through the first switch door 4. Therefore, as shown in fig. 2, when the electronic control board 2 needs to dissipate heat, the first switch door 4 can be controlled to open the air outlet 12. As shown in fig. 7, when the electronic control board 2 does not need to dissipate heat, the first switch door 4 may be controlled to close the air outlet 12, so as to effectively prevent dust and impurities outside the housing 1 from entering the housing 1 through the air outlet 12.
As shown in fig. 1, 3 and 8, in some embodiments of the present invention, the first switch door 4 includes a connecting rod 41 and a plurality of first air deflectors 42, each of the first air deflectors 42 is rotatably disposed on the housing 1 to open or close the air outlet 12, and the connecting rod 41 and the plurality of first air deflectors 42 are rotatably connected to enable the plurality of first air deflectors 42 to rotate synchronously. Therefore, the first opening and closing door 4 has a simple structure, the first opening and closing door 4 opens or closes the air outlet 12 by rotating the plurality of first air deflectors 42, and the arrangement of the plurality of first air deflectors 42 can control the flow direction of the air flow discharged from the air outlet 12 to a certain extent. It can be seen that the rotation of the first air deflectors 42 is synchronized, and the opening angle of the outlet 12 is also the same.
As shown in fig. 1, in some embodiments of the present invention, the first opening/closing door 4 further includes a first driving member 43, the first driving member 43 is disposed on the connecting rod 41 to normally drive the connecting rod 41 to move to the position where the plurality of first air deflectors 42 close the air outlet 12. It can be understood that, in the embodiment of the present invention, as shown in fig. 7 and 8, when the first switch door 4 is not acted by external force, the plurality of first air deflectors 42 are under the action of the first driving element 43 to close the air outlet 12, so as to effectively prevent dust, impurities and the like outside the casing 1 from entering the casing 1 through the air outlet 12. It can be understood that, as shown in fig. 2 to 4, when the heat dissipation fan 3 works, the gas in the housing 1 flows to the air outlet 12 under the action of the heat dissipation fan 3, so that the gas pressure inside each first air deflector 12 is greater than the gas pressure outside each first air deflector 12, and thus a gas pressure difference is formed between the inside and the outside of each first air deflector 42, that is, the gas pressure inside each first air deflector 42 is greater and the gas pressure outside each first air deflector 42 is smaller, so that under the action of the gas pressure difference, the gas flow pushes the plurality of first air deflectors 42 to move toward the direction of opening the air outlet 12 (that is, the plurality of first air deflectors 42 rotate outward), so that the plurality of first air deflectors 42 drive the connecting rod 41 to overcome the driving force of the first driving member 43, and thus the air outlet 12 can be opened. As shown in fig. 7 and 8, when the heat dissipation fan 3 stops working, the air pressures inside and outside each first air guiding plate 42 are equal, so that each first air guiding plate 42 is not subjected to an external force, and at this time, the first driving member 43 drives the connecting rod 41 to move to the position where the plurality of first air guiding plates 42 close the air outlet 12.
It should be noted that the first opening/closing door 4 may also be disposed at the air inlet 11, and the manner of disposing the first opening/closing door 4 at the air inlet 11 may be the same as that of disposing at the air outlet 12, and will not be described herein again.
As shown in fig. 3-4, in some embodiments of the present invention, the housing 1 is provided with a first limiting protrusion 13, the first limiting protrusion 13 is located at the air outlet 12, and when the plurality of first air deflectors 42 rotate to be perpendicular to the plane of the air outlet 12, the first limiting protrusion 13 is adapted to stop against one of the plurality of first air deflectors 42 close to the first limiting protrusion 13. For example, as shown in fig. 3 and 4, the first limiting protrusion 13 is located on the left side of the air outlet 12, and when the leftmost one of the first air deflectors 42 rotates to be perpendicular to the plane of the air outlet 12, the left side of the leftmost first air deflector 42 abuts against the first limiting protrusion 13. Therefore, the first air deflectors 42 can be effectively prevented from continuously rotating, and the known plurality of first air deflectors 42 can synchronously rotate, so that when one first air deflector 42 cannot continuously rotate, other first air deflectors 42 cannot rotate, the area of the plurality of first air deflectors 42 for opening the air outlet 12 is ensured to be the largest, the flow of air flow is accelerated, the heat dissipation of the electric control plate 2 is accelerated, and the reliability of the controller 10 is improved.
As shown in fig. 2 and 7, according to some embodiments of the present invention, the controller 10 further includes a second switch door 5, and the air inlet 11 is provided with the second switch door 5 to open or close the air inlet 11 through the second switch door 5. Therefore, as shown in fig. 2, when the electronic control board 2 needs to dissipate heat, the second switch door 5 can be controlled to open the air inlet 11. As shown in fig. 7, when the electronic control board 2 does not need to dissipate heat, the second switch door 5 may be controlled to close the air inlet 11, so that dust and impurities outside the housing 1 may be effectively prevented from entering the housing 1 through the air inlet 11.
As shown in fig. 1, in some embodiments of the present invention, the second switch door 5 includes a second air guiding plate 51 and a second driving member 52, the second air guiding plate 51 is rotatably disposed on the housing 1, and the second driving member 52 is disposed on the second air guiding plate 51 to normally drive the second air guiding plate 51 to close the air inlet 11.
Therefore, the structure of the second switch door 5 is simple, the second switch door 5 can open or close the air inlet 11 through the rotation of the second air deflector 51, the arrangement of the second air deflector 51 can also control the direction of the air flow flowing into the housing 1 from the air inlet 11 to a certain extent, and meanwhile, the second switch door has a certain guiding effect on the air flow.
Meanwhile, it can be understood that, in the embodiment of the present invention, as shown in fig. 7 and 9, when the second switch door 5 is not acted by external force, the second air guiding plate 51 is in a state of closing the air inlet 11 under the action of the second driving member 52, so as to effectively prevent dust, impurities and the like outside the casing 1 from entering the casing 1 through the air inlet 11. It can be understood that, as shown in fig. 2 and fig. 5, when the heat dissipation fan 3 works, the heat dissipation fan 3 rotates, the gas in the housing 1 flows to the air outlet 12 under the action of the heat dissipation fan 3 and is discharged through the air outlet 12, so that a negative pressure is formed in the housing 1, and thus a pressure difference is formed between the inner side and the outer side of the second air deflector 51, that is, the pressure of the gas inside the second air deflector 51 is lower, and the pressure of the gas outside the second air deflector 51 is higher, so that under the action of the pressure difference, the gas flow pushes the second air deflector 51 to move toward the direction of opening the air inlet 11 (that is, the plurality of second air deflectors 51 rotate inward) to overcome the driving force of the second driving member 52, and thus the air inlet 11 can be opened. As shown in fig. 7 and 9, when the heat dissipation fan 3 stops working, the air pressures inside and outside the second air guiding plate 51 are equal, so that the second air guiding plate 51 is not subjected to an external force, and at this time, the second driving member 52 drives the second air guiding plate 51 to rotate to a position for closing the air inlet 11.
It should be noted that the second switch door 5 may also be disposed at the air outlet 12, and the manner of disposing the second switch door 5 at the air outlet 12 may be the same as that of disposing at the air inlet 11, and will not be described herein again.
As shown in fig. 5 and 6, in some embodiments of the present invention, the housing 1 is provided with a second limiting protrusion 14, the second limiting protrusion 14 is located at the air inlet 11, and when the second air guiding plate 51 rotates to be perpendicular to the plane of the air inlet 11, the second limiting protrusion 14 is adapted to stop against one side of the second air guiding plate 51. Therefore, the second air deflectors 51 can be effectively prevented from continuously rotating, so that the area of the plurality of second air deflectors 51 for opening the air inlet 11 is ensured to be the largest, the airflow flowing into the shell 1 in unit time is increased, the heat dissipation of the electric control plate 2 is accelerated, and the reliability of the controller 10 is improved.

It is thus understood that the cooling fan 3 can be arranged in the housing 1 via the fan mount 6. Meanwhile, the heat dissipation fan 3 is opposite to the air outlet 12, so that the air flow in the shell 1 can be accelerated to flow to the air outlet 12, and then flow out of the shell 1. That is to say, can accelerate the heat exchange efficiency of air current and automatically controlled board 2 in the casing 1 to a certain extent, and then accelerate the heat dissipation cooling of automatically controlled board 2, improve the reliability of controller 10.
Specifically, as shown in fig. 1, 2 and 7, the air outlet 12 is disposed on the top wall of the housing 1, the air inlet 11 is located below the air outlet 12, and the air inlets 11 are disposed on the side wall of the housing 1 at intervals. Known, the air current that enters into in casing 1 carries out the heat transfer back with automatically controlled board 2, and the temperature of air current can rise, and the air current of high temperature can be natural upwards flow, and then the position setting of air outlet 12 is favorable to improving the flow velocity of air current in casing 1, and then accelerates in casing 1 air current and automatically controlled board 2's heat exchange efficiency. The arrangement of the air inlet 11 is beneficial to improving the flow rate of the air flow flowing into the shell 1 in unit time, and further, the heat exchange efficiency between the air flow in the shell 1 and the electric control plate 2 can be accelerated.
